print_cpuinfo() in board init code requires uclass CPU driver,
add it to be able to display CPU info when CONFIG_DISPLAY_CPUINFO
option is enabled. CPU node in DT will have to include 'clocks'
and 'u-boot,dm-pre-reloc' properties for generic print_cpuinfo()
to work as expected. The driver outputs info for i.MX8QXP Rev A
and Rev B CPUs.

Rather than passing a hardcoded maxsize to the generic get_ram_size()
function use the i.MX 7 specific imx_ddr_size() function, which extracts
the memory size at runtime by reading the DDR controller registers.

This is a purely cosmetic change as the generic get_ram_size() function
already took care of properly automatically detecting 256MB, 512MB or 1GB
modules.
